• golcadomide post CAR T-cells · EXPERIMENTAL · 0.3 mg - Per Os - every week - 6 months

This study is an open-label, multicenter, proof of concept, phase 2 trial. Patients will be recruited over 18 months. Safety analysis will be performed with a stop of the enrollment after 3 patients have either 1 complete treatment cycle or permanently discontinued treatment whichever occurs first. Approximatively 65 patients with aggressive large B-cell lymphoma (LBCL) (including diffuse large B-cell lymphoma (DLBCL), Primary mediastinal B-cell lymphoma (PMBCL), any transformed follicular or marginal zone lymphoma, high-grade B-cell lymphoma (HGBL)) will be enrolled in the study. The duration of treatment with golcadomide (CELMoD) is 24 weeks with 6 cycles of 28 days (4 weeks), starting at 5 days after CAR-T cells infusion. The primary objective of the study is to estimate the efficacy of golcadomide administered post-anti-CD19 CAR T-cell infusion, Efficacy determination will be based upon the primary endpoint of complete metabolic response (CMR) rate at 3 months after infusion of anti-CD19 CAR T-cell assessed by study investigator.
